Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes a prime mover equipped with a motor such as a tiller, which is available in many farmers, and by attaching and detaching a bean cutting mechanism as an attachment, each farmer can easily cut beans. The purpose of the present invention is to provide a bean cutter that can be configured as a machine.

As a device for attaching and detaching a working machine as an attachment to the above-mentioned self-propelled machine, the one described in Japanese Utility Model Publication No. 22404 is known.

However, what is disclosed is a reaping and threshing machine, the working machine of which is arranged parallel to the length of the grain machine. This parallel arrangement is not applicable to the bean cutter that is the object of the present invention.

This is because when using a self-propelled machine as described above, mowing is limited to one row, so the wheels must be positioned in the valleys on both sides of one row. In this case, the lengths of the reaping mechanism and the self-propelled machine would coincide, making it impossible to construct the reaping mechanism. An object of the present invention is to solve this problem and provide a bean cutter using a self-propelled machine. Also, since water tends to accumulate in valleys, cut birch trees need to be placed on top of ridges.

The present invention easily achieves this objective. In addition, the reaping device has a reaping section located in front of the center between the left and right wheels of an engine-equipped target machine, and the reaping section is placed so that the rear part of the conveyor belt is positioned above one of the wheels.
